不同干扰对北斗B1I信号接收机影响
|
摘要
目前,国内对于北斗卫星信号质量的评估多集中在空间段和地面段,然而对于干扰条件下,用户端的性能研究却不多见。为了对干扰有效划分,结合接收机基带信号处理过程,根据相关器积分时间与北斗B1I信号的频谱特性,将干扰分为4类,并导出相应的解析表达式,最后分析了连续波干扰下载波跟踪测量误差和码跟踪测量误差。北斗B1I信号的仿真结果与国外文献提供的GPS L1的仿真结果具有良好的一致性,验证了此方法的有效性。同时,对于不同干扰类型的研究有助于北斗接收机的抗干扰设计。
At present,domestic evaluation of Beidou satellite signal quality mostly concentrates on the space segment and the ground segment.However,research concerning the performance of the user end under interference is rare.In order to classify the interference effectively,combined with the receiver baseband signal processing process,the interference is categorized into four categories based on the correlation time of the correlator and the spectral characteristics of the Beidou B1 Isignal,and the analytical expressions are derived as well.Finally,the analysis is performed regarding carrier tracking measurement error and code tracking measurement error under continuous wave interference.The simulation results of the Beidou B1 Isignal are in good agreement with the simulation results of GPS L1 provided by foreign studies,thus verifying the effectiveness of this method.The research about different interference types can benefit the anti-jamming design of the Beidou receiver.
